The invention has only to be deemed “more likely than not” to work in order to receive initial approval. And, although thousands of patents are challenged in court for other reasons, no incentive exists for anyone to expend effort (ii) the science of an erroneous patent. For this reason the endless stream of (iii) devices will continue to yield occasional patents.

Erroneous patent does not mean they are bogus(fake) devices right? and what do "yield occasional patents" and "more likely than not" mean?

Hi Lingyi,
"Erroneous patents" does not refer to fake devices. Instead, it refers to a patent for a device that will not work or will not do what it promises to.
"Yield occasional patents" means "lead to occasional patents." In other words, all of the continuous "bogus" devices (which don't work) will still be given patents sometimes.
"More likely than not" is just another way of saying "probably."
I hope this helps!

Happy to help! The correct answer is (H) bogus. For this blank, we're looking for a word with a similar meaning as phony to describe devices that don't work. The second sentence tells us that there isn't much motivation for people to challenge these erroneous patents, which suggests that some such bogus devices will continue to get patents.
